Founding Engineer

About this role

ABOUT THE ROLE We're an early-stage, fast-growing enterprise AI platform (agentic operating system for businesses) that has achieved strong product-market fit and is growing revenue rapidly. Backed by Y Combinator and prominent angel investors from the AI and SaaS world, we have thousands of AI agents deployed at scale-up startups and enterprise companies today. This is a founding engineer role — you'll operate at near-CTO level, taking vague problems all the way to shipped product with no hand-holding. You'll be backend-heavy and AI-native, but fully capable of going full-stack when needed. If you've ever wanted to shape a product and company from the ground up, this is that seat. WHAT YOU'LL DO - Own large product areas end-to-end — from user insight through to production - Build and continuously improve our agentic systems: accuracy, reliability, and capability - Work at the frontier of AI engineering — context engineering, tool use, and agent architectures - Talk directly to users, understand their pain points, and scope features that actually solve problems - Ship full-stack when needed: Go backend, React + Vite (TypeScript) frontend - Champion AI-first development practices — coding agents, automation, and ruthless self-scaling - Review code quickly while maintaining high standards across the codebase - Design and work with APIs (REST and/or gRPC) in microservices architectures - Own CI/CD pipelines, automated testing, deployment workflows, and production observability WHAT WE'RE LOOKING FOR Must-haves: - Proven production experience building backend services in Go (Golang) — this is a dealbreaker - Authorized to work in the United States without visa sponsorship - Experience building frontend applications with React and TypeScript - Hands-on experience with CI/CD pipelines, automated testing, and production monitoring/observability - Experience building and consuming APIs (REST and/or gRPC) in microservices environments - 0–3 years of professional software engineering experience (full-stack or equivalent) Strong pluses: - Experience with cloud platforms (AWS, GCP, or equivalent) and containerization (Docker, Kubernetes) - Prior experience with AI infrastructure, prompt engineering, model deployment, or agent orchestration - Experience designing and shipping AI-driven products; familiarity with agentic AI systems, LLMs, or AI agents - Previous startup experience or a founding/early engineer background - Experience with relational databases (Postgres/MySQL) and NoSQL, with solid understanding of data storage trade-offs - AI research background or experience at an AI tooling/coding startup - Former founder — or someone who has built something meaningful from scratch (startup, side project, shipped feature) - Bachelor's degree in Computer Science, Engineering, or equivalent practical experience You thrive if you: - Are a sharp, autonomous problem-solver who doesn't need a PM to decide what to build - Have deep product sense and build for users, not for code's sake - Are obsessed with using and building AI-first development tools (e.g. Claude Code, Cursor, coding agents) - Love clean, maintainable Go and hold high standards in code review - Thrive in ambiguity and move fast without sacrificing quality COMPENSATION & BENEFITS - Salary: $120,000 – $250,000 USD annually, reflecting the outsized impact of this founding role - Equity: Generous equity package commensurate with a founding-level position - Unlimited AI tooling budget — we practice what we preach - A seat at the table: you will shape the product and the company's direction LOCATION - On-site in San Francisco, CA - Visa sponsorship is not available — candidates must be authorized to work in the United States
